understand winter operability of #2 Ultra Low Sulfur Diesel
24/7 Travel Stores have done fuel testing and research. We have assembled the following guidelines to help our customers better understand winter operability of #2 Ultra Low Sulfur Diesel. This is only a guide; no warranty is implied.
When does 24/7 Travel Stores treat diesel?
Besides proper additive use, what else can I do to protect equipment from downtime during severely cold temperatures?
Why do we only use #1 diesel in extreme cold?
How exactly does an additive keep diesel fuel from gelling?
Why have I checked the fuel for water using “water tape/paste” and found no water, but have been advised of, or experienced a moisture problem?
How can I distinguish moisture related issues vs. wax/fuel related issues?
What is the proper procedure for additizing my fuel?
At moderately cold temperatures, the diesel fuel can appear cloudy. Is this normal?
If I experience gelled fuel or problems with ice in fuel filters or fuel lines, what do I do?
What types of equipment can contribute to winter operability problems?
COLD FILTER PLUGGING POINT F (CFPP)
Determines the cold-weather operability limit of the fuel.
POUR POINT F (PP)
Determines the temperature that wax begins to drop out of the fuel.
A.P.I. GRAVITY (API GRAV.)
Determines the gravity or density of the fuel, related to heat content, affecting powder and economy.
WATER CONTENT PPM (H2O, PPM)
Determines the amount of water entrained in the fuel sample.
